The White House and Congress are supposed to coordinate on policy, not on crime.

in a nutshell;

...this is full on kabuki theatre.

White House feeds Nunes cherrypicked intelligence information.
Nunes “discovers” the intelligence very publicly.
Nunes races to the White House with the full compliment of media to share what he “discovered.”
White House releases his discovery.

The whole thing is choreographed to make the investigation into Trump look illegitimate. Obstruction, obstruction, obstruction.
